General description

Cyclopentanecarboxaldehyde can be prepared from cyclohexene, via copper-catalyzed oxidation with persulfate. It can also be synthesized from mercuric sulfate and cyclohexene.

Application

Cyclopentanecarboxaldehyde may be used in the synthesis of:
  • D,L-trans-2-cyclopentylmethylene-1-nitroso-1-(2-hydroxycyclohexyl)hydrazine
  • ethyl 5-cyclopentyl-5-hydroxy-2-pentenoate
  • ethyl 3-cyclo entyl-3-hydroxy-2-vinylpropanoate
